In my opinion, no it only is good for putting your opponent to sleep and a body slam. There aren't many other effective moves for a jiggly puff.
As a Pokemon character, you should never get a Jigglypuff. Jigglypuff is a very weak normal type Pokemon, and pretty much every normal type Pokemon is what you should avoid. Jigglypuff's evolved form, Wigglytuff, is still not that much better and can easily be defeated with a fighting-type move.
Actually, if you train Jigglypuff to a very high level (i.e level 80) it can be a very strong Pokemon if you evolve it with a Moon Stone. The HP that Wigglytuff and Jigglypuff have are highly above average and can rival and even beat legendary Pokemon on Hp stats. I am pretty sure it can learn Focus Punch and Body Slam so it can be a very useful Pokemon if you use it right.
As a Super Smash Bros. Character, if you know how to use Jigglypuff, she is one of the best characters.
You use a Moon Stone.
no its a regular Pokemon like a meowth
in the safari zone :) Or on Route 3 and 4

Give it a moon stone. (level doesn't matter.) I think you can find one at mount moon in the kanto region.
Jiggly puff does not evolve at a level, but by using the moonstone.
